[SVN] r10439 (R)

Modified Rmate approach:
- usage of scriptmate my_popen3 method
- R slave's stderr is redirected to stdout
-- in order to synchronize warning messages for instances
-- error messages and warning messages are caught by regexps
- the prompts '>' and '+' and now hyperlinked to the source code line
-- this only works for source code coming from the doc; imported R code lines destroys up to now the linkage
- if an error occurs now the last line is:
-- Execution halted at line ?? (implemented as hyperlink)
- comments are shown in italics blue
- recursive deleting of a path function is now an UNIX shell command
- ESC now cancels the current job by closing the output window
- STDOUT is again set to sync = TRUE
- restructuring of the entire source code
